Present: CW, HT, TD, TN

== Summary of actions ==


 
== Notes ==
1. //Introduction, [wiki:Research/GaborLens/Meetings/2020/10/15 notes and actions]//: **CW/All**
 * TN - Summary of progress on paper draft
  * Working with TD to incorporate recent results into paper
  * Recent meeting developed some output suitable for inclusion – final decisions with KL
  * Some evidence TD results may reproduce non-uniform intensity on rings – as seen in expt – worth further exploration but not at expense of delaying paper.
2. //[raw-attachment:meeting_HTL_221020.pdf Updates on the particle generation]//: **HT**
 * Good progress on Smilei convergence testing – appropriate parameters now determined
 * Initial e temperature dependence simulations
  * Results broadly similar with increasing temperature
  * Trends are seen but peak energy dependence is not strong.
 * Tracking of 3D smeared particle distributions shows ‘unphysical’ features which cause further features downstream, however average beam charactersitics are not strongly influenced.
 * Beam tuning to account for new input parameter started – good improvements seen even though work is not complete.
3. //Updates on simulation of "IC" lens//: **TSD**
 * Introduce ‘electron beam’ almost tangential to electron cloud in lens to study potential to drive off axis plasma non-uniformity.
 * Fighting simulation instability with some success justifying further effort
 * Macro-particle management techniques (statistical merge/weighting) are available in Vsim, not tried yet, but may need to explore in future
